Paul, Weiss, Rifkind, Wharton & Garrison LLP

The Washington DC-based appellate practice at Paul, Weiss, Rifkind, Wharton & Garrison LLP is distinguished by its management of high-stakes corporate and constitutional disputes of national importance. The group frequently represents large co-defendant groups in major litigation and is led by the ‘phenomenal oral advocate’ Kannon Shanmugam, who has appeared before the US Supreme Court 39 times. Shanmugam, regarded as a ’fantastic strategist’, recently acted for Meta in a high-profile US Supreme Court securities appeal and achieved a first-of-its-kind Fifth Circuit victory that overturned federal sanctions against an open-source privacy software project. He is supported by ‘standout’ partner Masha Hansford, a former Assistant to the Solicitor General with extensive experience in significant bankruptcy and administrative law appeals. William Marks further strengthens the team’s capabilities in civil and criminal litigation, focusing on antitrust, securities, and class certification, having represented clients in 15 merits cases before the US Supreme Court.
